Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0037] Such as Figure 5 As shown, the user uplink data scheduling method of the embodiment of the present invention is applied to the second type of uplink and downlink time slot ratio matching mode TDD DL / UL subframe configuration 1 in the 3GPP long-term evolution time division duplex system to support multi-period TTI bundling Mode semi-persistent scheduling, including the following steps:

[0038] Step 202, starting with the first uplink subframe allocated by semi-persistent scheduling, sequentially setting every four adjacent uplink subframes as a TTI bundle;

[0039] Step 204, setting the semi-persistent scheduling period offset delta in the multi-period mode;

[0040] Step 206, determine the periods T1 and T2 of the multi-period mode semi-persistent scheduling of two adjacent TTI bundles according to delta;

[0041] Step 208: Scheduling user uplink newly tr...

Abstract

The invention discloses an user uplink data scheduling method and user equipment, which is applied to TTI bundling-supporting multicycle mode semi-persistent schedule under the second downlink and uplink time slot proportioning mode TDD DL / ULsubframe configuration 1 in a 3GPP long-term evolution time division duplex system; the user uplink data scheduling method comprises: starting from the first uplink subframe distributed by the semi-persistent schedule, and setting the subframe of adjacent four uplinks to be TTI bundle; setting the multicycle mode semi-persistent scheduling cycle offset ofTTI bundle; confirming the cycle of multicycle mode semi-persistent schedule of adjacent two TTIbundles according to the offset; and scheduling user uplink newly-transmit packet data according to the multicycle mode semi-persistent schedule cycle. The invention solves the problem of the conflict between multicycle mode semi-persistent schedule retransmit packet and newly-transmit packet, and reduces the signaling cost of TTI bundling supporting VoIP and other businesses.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a user uplink data scheduling method and user equipment applied to 3GPP LTE TDD DL / ULsubframe configuration 1 and supporting TTI bundling. Background technique [0002] Semi-persistent scheduling is a new scheduling method proposed in 3G LTE (Long Term Evolution, long-term evolution) in order to save the physical downlink control channel (PDCCH), initially mainly for VoIP (Voice over IP, IP-based voice transmission) business proposed. The basic idea of ​​semi-persistent scheduling (semi-persistent scheduling, SPS) is that since the arrival interval of a new VoIP service packet is 20 ms, it can indicate the cycle of reserving resources through Radio Resource Control (RRC) signaling , and then activate the reserved time-frequency domain resources through a PDCCH, and then automatically use the fixed-position resources to transmit data every 20ms, without using the PDCCH...
