In the downlink, a group of base stations (BSs) coordinately transmit the users\u2019 data to avoid serious interference at the users in the boundary of the cells, thus substantially improving area fairness. However, this comes at the cost of high feedback and backhaul load; In a frequency division duplex system, all users at the cell boundaries have to collect and send feedback of the downlink channel state information (CSI). In centralized JT-CoMP, although with capabilities for perfect coordination, a central coordination node have to send the computed precoding weights and corresponding data to all cells which can overwhelm the backhaul resources. In this paper, we design a JT-CoMP scheme, by which the sum of the mean square error (MSE) at the boundary users is minimized, while feedback and backhaul loads are constrained and the load is balanced between BSs. Our design is based on the singular value decomposition of CSI matrix and optimization of a binary link selection matrix to provide sparse feedback\u2014constrained backhaul link. For comparison, we adopt the previously presented schemes for feedback and backhaul reduction in the physical layer. Extensive numerical evaluations show that the proposed scheme can reduce the MSE with at least\n                    <jats:inline-formula>\n                      <jats:alternatives>\n                        <jats:tex-math>$$25\\%$$<\/jats:tex-math>\n                        <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\">\n                          <mml:mrow>\n                            <mml:mn>25<\/mml:mn>\n                            <mml:mo>%<\/mml:mo>\n                          <\/mml:mrow>\n                        <\/mml:math>\n                      <\/jats:alternatives>\n                    <\/jats:inline-formula>\n                    , compared to the adopted and existing schemes.\n                  <\/jats:p>","DOI":"10.1186\/s13638-021-01979-3","type":"journal-article","created":{"date-parts":[[2021,4,23]],"date-time":"2021-04-23T06:04:14Z","timestamp":1619157854000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["MSE minimized joint transmission in coordinated multipoint systems with sparse feedback and constrained backhaul requirements"],"prefix":"10.1186","volume":"2021","author":[{"given":"Mohammad Bagher","family":"Nezafati","sequence":"first","affiliation":[]},{"given":"Mehrdad","family":"Taki","sequence":"additional","affiliation":[]},{"given":"Tommy","family":"Svensson","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2021,4,23]]},"reference":[{"issue":"3","key":"1979_CR1","doi-asserted-by":"publisher","first-page":"30","DOI":"10.1109\/MVT.2015.2446420","volume":"10","author":"K Manolakis","year":"2015","unstructured":"K.
